The Golden Rule is based on the principle that you should treat others the way you would like to be treated yourself.

There is also solid, scientific proof that people who give to others are generally happier people.

When you do something kind or thoughtful for someone else, you are, in essence, giving them something. And we all would prefer it if other people treated us with kindness and thoughtfulness, wouldn’t we?

So performing small acts of kindness is a win-win situation. Everybody benefits. Everybody is happier.

Here’s a repertoire of random acts of kindness we can all keep in mind as we go about our days. Some of them may cost you a bit, some of them may come free.
